I have my app ready and when I tested it on iPad running iOS 6.0.1 with orientation mode enabled, the resize doesn't work correctly.

If I start app in portrait mode, it's good but as soon as it goes to landscape, it doesn't resize for landscape and stays the viewport to the size of portrait. The same goes for the other side. If I start my app in Landscape, it's good but as soon as it goes to portrait, it doesn't resize and things go out of screen.

sorry but i dont know anything about that charts because i dont need to use that But i think it is about showing charts in portrait mode the charts doest show fully so it need to scale the chart but when u change to landscape chart show it self fully and no need to scale it self...
